NJ Well Driller study plan

Distinguish rotary, cable-tool, air-rotary, and hollow-stem auger methods and state which formations and casing conditions each suits in New Jersey Coastal Plain versus Piedmont bedrock

Identify the function of each major rig component (mast, swivel, kelly, casing hammer, mud pump, air compressor) and the failure mode it prevents

Explain how drilling method choice affects borehole stability, grout placement feasibility, and ultimate well yield

Relate aquifer type (unconfined sand and gravel, confined layered Coastal Plain, fractured bedrock) to screen or open-hole interval decisions

Compute annular seal volume and grout quantity from borehole diameter, casing OD, and seal depth, showing unit conversions

Specify casing diameter, wall thickness, and material for a stated design yield and pump setting depth

Lay out screen length, slot size, and gravel pack gradation for a screened well in a stratified sand aquifer

Sequence well construction steps from site prep through development and disinfection, noting inspection hold points

Compare development methods (surging, bailing, jetting, air-lifting, overpumping) and match each to well type and screen material

Diagnose a set of rehabilitation symptoms - declining specific capacity, sand production, iron bacteria - and select a treatment approach for each

Calculate specific capacity before and after development to quantify improvement

Explain how development affects filter pack settling, screen plugging, and grout integrity

Match pump type (submersible, lineshaft turbine, jet, variable frequency drive) to setting depth, yield, and drawdown conditions

Read a pump curve and select an operating point within the allowable range for a stated total dynamic head

Compute drawdown, pumping water level, and total dynamic head from static water level plus well losses

Size pressure tank and storage capacity for a given peak demand and pump cycle limit

Outline the New Jersey well permitting sequence - application, approval, construction notification, and final documentation - and identify who signs what at each stage

List the required contents of a well record (log) and completion report submitted to the state

Describe abandonment procedures for an unsealed flowing well, a screened well in sand, and a bedrock well, including seal material and verification

Identify which well construction and sealing activities require licensed oversight versus which may be delegated

Interpret a water quality panel (iron, manganese, hardness, nitrate, arsenic, bacteria, pH) and decide which results require treatment, retesting, or reporting

Select treatment trains for iron and manganese, hardness, nitrate, and arsenic, and state the maintenance each requires

Apply setback and contamination-prevention practices: wellhead protection, backflow prevention, grout seal, and disinfection of equipment

List personal protective and site safety controls for rig operations, confined spaces, and chemical handling

Assemble a complete well file: contract terms, change orders, well log, completion report, water test results, and abandonment record

Apply record retention and client confidentiality practices to a set of sample project documents

Re-derive specific capacity and drawdown from field notes to confirm reported figures reconcile

Audit a sample abandonment record for missing seal depth, material, or verification entries

Complete a timed 100-question mixed-domain practice set and score each domain separately

Re-teach the two weakest domains using your own notes and worked examples

Recompute grout volume, TDH, and specific capacity from scratch without reference to confirm retention

Build a one-page formula and reference sheet covering conversions, regulatory deadlines, and treatment thresholds
